Introduction: Oxygenation and Disease Interrelationships
Starts at 00:00
[00:01] Hello, everyone. It's great to see everyone on the call tonight. I have forgotten to press a record
button here. Fortunately, very early in the presentation. So I'm going to introduce again that we are
talking about some really good information tonight anemia coronary artery disease and heart failure.
And all 3 of those, although they are 3 distinct diseases, they all in their own way.
[00:29] Affect a person's oxygenation and so, oxygenation as I was explaining is the ability of the tissues
to be perfused, the organs and so, when oxygenated blood is released from the heart and out to the
body, oxygen is dropped off by products of CO2 things like that is picked up and taken back to the lungs
where it's released in the form of CO2.
[00:58] And so, so I guess my overall my overall premise tonight is that we're talking about diseases that
affect an overall oxygenation status of the individuals. And so it's important to understand the
similarities and how all these conditions affect oxygenation. And so we, you know, looking into
pathophysiology and.
[01:23] So that alteration in the diseases is going to cause the person to have signs and symptoms. And
that's where they show up to the nurse practitioner in the clinic. And you're thinking, okay, patient, let's
see, let me think about what was going on at that level of patho.
[01:43] And to determine what your diagnosis is and then how we can manage you. So that is a huge
relationship that I keep stressing each week in our webinars.

[01:55] Okay, and so why is it important to understand shared challenges in oxygenation among these
three diseases? Well, because you think about patients, we have to have a holistic approach of
managing the patient. It often takes a multidisciplinary team and face it.
[02:19] How many times have you had patients that had all of these at one time heart failure? Well,
maybe they had coronary artery disease that did lead to heart failure and they have anemia on top of
that. And so, yeah, so they can have so you've got three of these that is working against one individual
and they're in some form. They're going to have impaired oxygenation status.
[02:43] And so it's really helpful in terms of early detection and intervention because, you know, we can
screen for coronary artery disease before it even ever gets to a heart failure state stage. And so we can
screening is really important and we can provide proactive treatments lifestyle management symptom
management. Everything is done to improve oxygenation and reduce cardiac stress on the heart.
[03:10] And a lot of patient education, diet, nutrition, exercise, and hydration. But we're going to
separate these out in three different ways in just a few minutes. We'll talk about each of them. But over
the next I'm just really committed for bringing home the point about the relationship between anemia
coronary artery disease and heart failure before we actually talk about them separately.
[03:36] So with, so there's a relationship between anemia and coronary artery disease. So anemia can
actually exacerbate coronary artery disease by increasing myocardial o2 demand while simultaneously
reducing oxygen supplies. So anemia is what? Well,
[03:57] Remember that hemoglobin carries oxygen to the tissues. And so if the person is anemic, then
that's going to cause the body to...
[04:10] I'm not getting my kidneys or getting perfused. My my spleen is not getting perfused. My veins
and arteries are getting perfused. And so the heart automatically starts thinking, wait a minute, I need to
work harder to get the oxygen out. And so that's why there's an increased myocardial oxygen demand
because it's not getting to the tissues. There's not enough hemoglobin in the person that who has
anemia. And so
[04:40] Then the heart starts kicking in as a compensatory mechanism. And so it doesn't really help
because their person is anemic, but the heart does try to step in and help.
[04:53] alleviate that so it can lead to a lot more frequent and severe ischemic episodes, including cardiac
ischemic episodes, worsening coronary artery disease symptoms. And then actually impact there's also
an impact of coronary artery disease on anemia coronary artery disease can contribute to anemia
through chronic inflammation and reduced renal function which
[05:21] Impairs erythropoiesis red blood cell production. We'll talk a little bit more about erythropoiesis.
I'll mention a little bit more tonight, but when we get into week 4 and going into the renal information,
I'll mention it there as well.

[05:36] But anyway, that's a relationship there and also medications used to treat coronary artery
disease. We're always given the antiplatelet agents, Plavix, for instance, that can increase the risk of
bleeding and cause subsequent anemia. And then we have anemia and heart failure. There's a
relationship here as well. So the impact of anemia on heart failure anemia will
[06:05] Increase the cardiac workload as I was mentioning just a few seconds ago as the heart
compensates for reduced
[06:13] oxygen-carrying capacity by pumping more blood. And so this leads to worsening heart failure
symptoms and the progression of the disease. And then we have the impact of heart failure on anemia.
So heart failure can cause anemia through, again, chronic inflammation. And remember, we talked
about the hypersensitivity actions last week, and we talked about, you know, inflammation, the
inflammatory process and things like that. We can't ever with all of our diseases.
[06:42] I'll always take you back to the immune system and how it's impacts just about, it's a part of just
about every disease process. And I'll point that out when that happens, but this is one of them where
there's a lot of chronic inflammation, renal issues, and also the use of diuretics which can help to lead to
iron deficiency anemia.
[07:06] The thinking about that as well. And so there's basically a reduced cardiac output and heart
failure, impairs renal function because it is not the kidneys are not being perfused. And so that's going to
further contribute to the anemia.
[07:25] And then we have a relationship between coronary artery disease and heart failure. And so that
impacts coronary artery disease on your well aware of this is a leading cause of heart failure. The
reduced blood flow from narrowed or blocked arteries just deprives the heart muscle of oxygen, which
leads to ischemia and weakening of the heart muscle.
[07:52] Over time, this can result in heart failure as the heart struggles to pump blood effectively. So
that's that is the impact of coronary artery disease on heart failure. Now the impact of heart failure on
coronary artery disease heart failure can actually worsen CAD by increasing the myocardial oxygen
demand and reducing coronary perfusion.
[08:16] And so basically, that's a compensatory mechanism. The same thing I was just mentioning early
and heart failure such as increased heart rate and blood pressure can exacerbate the progression of
atherosclerosis.
[08:28] Yes, I love some of the things I'm saying coming across the chat there. All right. And so with those
relationships, kind of set the stage for that. And, you know, we're talking about the impact of all this on
the body's oxygenation. Let's just go on into the, you know, talk about these separately. So I'll talk a little
bit about some terms here when you're trying to classify anemia.
